[Pw_forum] Fw: nimage is larger than the available number of images?

Ok, I figured out what I did to myself. Unless the first and last images are being optimized (done by setting first_last_opt to .TRUE. in the &IONS namelist), then the number of images available to be parallelized is two less than num_of_images, so if num_of_images = 7, then nimage <= 5.
